Ponzos Time Machine is updated each week by the ETF Prophet blog. The updated analysis replaces the old analysis each week, and the blog does not maintain a past archive of the analysis results.
Each week I post the index forecast from the PREVIOUS WEEK as a way of archiving the results over time. The analysis also provides a good guideline for trading over the coming weeks based on historical performance.
You can check out all the great commentary and the current time machine analysis at ETF Prophet by clicking on the link in my blog roll. It is an excellent site worth following.
